Definitions
- Cable sleeve made of a shrinkable sleeve and a protective cover.
- the invention relates to a cable sleeve of a shrinkable envelope and an Schutzemlage from a re ⁇ tively rigid, tubular central portion and on both sides tapered at the ends ⁇ sen end portions.
- a protection and Isoliervor ⁇ direction is known, which is arranged inside a cable sleeve. It consists of a relatively rigid, tubular middle part and end parts attached or attached to both ends thereof. The end parts have several flexible tongues, with which a conical transition from the cylindrical middle part to the inserted cables can be created.
- This protection and insulation device primarily offers protection for a splice which is involved in the cable sleeve.
- a shrinkable cover is shrunk over this protective and insulating device.
- This protective insert is made of metal and nevertheless does not offer sufficient permeation protection for all cases due to the many long slots, especially in the end areas.
- This protective device consists of a layer of fiber material between a permeationsdic th metal layer and a polymer layer provided with micro punches is placed ⁇ st. Through these micro holes gases to escape, which sat within the fiber Mater as during the Schrumpfvorgan ⁇ be free. A covering is shrunk over this protective device. In this case, a place pending on the inside be ⁇ sealant is melted and a compound Zvi ⁇ rule of the sheath and the protector made. If the cable sleeve must be opened for repair or service work, the guard can not be comparable turns as they ren together with the non Careverwendba ⁇ shrinkable sleeve must be removed.
- the object of the present invention is to provide a shrinkable cable sleeve with a protective insert which offers sufficient mechanical protection and continuous protection, the structure of the protective cover and a permeation barrier being designed with the simplest possible means and at least the mechanically supporting part of the protective cover is to be used again.
- a cable sleeve of the type described in the introduction in that a film as a permeation barrier covers the middle part and the two end parts of the protective cover between the shrinkable cover and the protective cover, the film being so flexible that the shrinking of the cover is not hindered and the film can be pressed tightly against the protective cover by the shrinking covering.
- a decisive advantage of the invention compared to the prior art is that a protective insert is used in the cable sleeve with a shrinkable sheath, which is based on minimal effort and which forms a closed permeation barrier in cooperation with a simple, all-covering, separate film.
- the film is a continuous flat structure, for example as a sheet material without openings, slots or perforations, so that over the entire th is given by the Schutzemlage region covered a volliffi ⁇ ger and safer Permeationstik.
- the mechanical ⁇ specific part of the Schutzemlage is a flat paperboard formations from simp ⁇ work piece materials such as Faserpreßstoff or hard; but it can also be used for special applications
- the film Since the film is applied as a separate part over the mechanically supporting protective cover, the protective cover can be used again after repair or service work. Only the film has to be replaced, since when the cable sleeve is opened it adheres to the inner surface of the shrinkable covering, which may be coated with sealant or hot melt adhesive.
- the film itself is not shrinkable. However, it is flexible enough to nestle tightly under the shrinking envelope against the protective sheet without impeding the shrinkage of the envelope. A rough adjustment in the end areas can already be made by molding when placing the film.
- the film has sufficient permeation values and the water vapor permeability value is less than 1 g / m 2 and day. In the simplest case, the film has a single-layer structure made of aluminum with a thickness of 5 ⁇ m to 50 ⁇ m.
- Composite foil with an aluminum layer is also suitable as a permeation barrier.
- Polyethylene terephthalate (PETP) is suitable as carrier film for this composite due to its tear resistance, temperature resistance and comparatively poor adhesion to hot melt adhesives.
- PETP polyethylene terephthalate
- Such a composite film can be removed from the shrinking covering after disassembly and disposed of separately. Furthermore, even under the heat transfer required for the shrinking, the PETP layer does not have a full-surface material bond with the protective cover.
- a sealable polyethylene layer is used instead of a PETP layer.
- the film can be delivered as a separate part or it can also be fixed in small areas on the protective insert, for example, for reasons of ease of assembly, for which hot melt adhesive is suitable, for example.
- the protective insert consists of a cylindrical middle part and an adjustable end part at each end.
- the end parts are used to compensate for the differences in diameter between the middle part that surrounds the splice and the inserted cables.
- the end parts can be designed, for example, as flexible tongues projecting from the central part in the axial direction, which are aligned in a conically tapering manner during the adaptation. Foldable end parts are also possible, that is to say the conical transition is achieved by folding the end regions, for example along predetermined fold lines.
- the protective insert can be made of smooth or corrugated material, with a corrugation in the axial direction expediently being preferred in the end regions for the adaptation.
- the material of the protective insert is preferably treated with water-repellent or water-absorbing components such as waxes.
- a sealant such as a hot-melt adhesive is applied to the inner surface of the shrinkable covering, which melts during the shrinking and, in addition to the sealing effect, also contributes to overall mechanical strengthening.
- Figure 1 shows the cable sleeve before installing the permeation-proof film.
- Figure 2 shows the cable sleeve after installation of the permeation-proof film.
- Figure 3 shows the fully assembled cable sleeve.
- Figure 4 shows the cross section of a composite film.
- the cable splice the Schutzemlage SE is completed already intra ⁇ half.
- the Schutzemlag SE with its cylindrical middle part MT and the two end parts ET is mounted, whereby it is indicated here that the end parts ET are formed from flexible tongues Z which have been bent conically to compensate for the diameter on the two cables K 1 and K 2 introduced.
- the protective cover SE is slit lengthways and is simply overlaid and optionally fixed along the long separation LSE.
- the end parts ET can also be converted from the cylindrical to the conical shape by appropriate folding, in which case there are no slots.
- the film F serving as a permeation barrier is wrapped as a separate mounting part around the already installed protective cover SE, the area of the film F being so large that it can span the entire arrangement. This also seamlessly covers the two end parts ET of the protective frame SE. In the prior art, however, there are leaks in these areas as a result of the slots in the protective cover coated with a water vapor barrier.
- the film F m acting as a permeation barrier has been wrapped around the protective cover over its entire length, with the shape of the conical end regions being shaped by molding before the cover shrinks.
- the film F can be nestled without damage due to its deformability, whereby it does not hinder the shrinkage of the casing still to be applied. However, it is caused by the shrinkage forces acting in the envelope during the subsequent shrinking process, firmly and tightly pressed onto the protective insert, so that the covering is tight.
- there is therefore only the longitudinal slot LF of the film F in which, if necessary, an additional seal can be achieved by a correspondingly large overlap, by introducing a sealant or by the melting sealant on the inner surface of the casing.
- Figure 3 finally shows the fully assembled cable sleeve KM with the shrunk-on sheath U and a longitudinal closure V of the type known per se.
- Figure 4 shows a film made of several layers as a composite film (VF). It consists of a layer S1 of up to 20 ⁇ m thick made of polyethylene (PE) or polyethylene terephthalate (PETP), a middle layer S3 of up to 12 ⁇ m thick made of aluminum and a further layer S3 which e.g. corresponds to the first layer S1.
